Place frozen pierogies in the crockpot.
In a medium saucepan, melt butter and fry onion on medium-low heat, until onion is golden brown.
Pour onion and butter over pierogies; add salt and pepper.
Cook, on high, for 3 hours.
A few times during cooking, use tongs and gently re-arrange pierogies and ladle butter sauce to cover pierogies on top.
Turn to low or keep warm once pierogies are cooked and/or butter sauce begins to bubble.
